It fits the GX780R, GX780R-i548LW7P, GX780R-024CS, GX780DX, and 84 additional variants. OEM part number BTY-M6D confirms correct fitment across the full GX780 line.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGX780 platform compatibility:\u003c\/strong\u003e\n    Every GX780 variant in this family shares the same 11.1V three-cell voltage rail, BTY-M6D connector pinout, and BMS handshake protocol. That common platform spec is why one cell fits all 84+ listed models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a GX780R under sustained GPU and CPU load. The BMS held voltage above 10.2V through discharge and triggered cutoff correctly at the low-voltage threshold — no premature shutdown during the stress cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the GX780R:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GX780R BIOS reports poor battery health after a fresh cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GX780R BIOS reads health data from the battery's EEPROM — a small memory chip that stores cycle count, rated capacity, and charge history. When a new cell arrives, that EEPROM data does not match the BIOS's learned profile for the old pack. The BIOS interprets the mismatch as degradation and flags the battery as poor or unknown. One complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough data to write a new baseline and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGX780R shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below what the CPU and GPU need under full load — even though the OS fuel gauge still reads 20–30%. The fuel gauge IC calculates remaining charge from a model built on the old cell; it hasn't recalibrated to the new chemistry yet. Under a gaming load spike, the actual cell voltage hits the BMS cutoff floor before the gauge reaches zero. Run two to three full discharge-and-charge cycles to let the fuel gauge IC recalibrate against the new cell — after that, the shutdown percentage should align with genuine cell depletion near 5–8V per cell group.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409811636314,"sku":"BWCS-MSE660HB-1","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409811669082,"sku":"BWCS-MSE660HB-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409811701850,"sku":"BWCS-MSE660HB-3","price":141.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSE660HB-1.webp?v=1779581059","url":"https:\/\/batteryweb.com\/products\/msi-gx780r-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
